' A l Application filed June 1, 1903. Serial No. 159,419. (No model.)

Zb LZZ whom it may concern/,1 Be it known that I, HERBERT H. DREW, a icitiz'enof the United States, and a resident of .lMaterloo, in thefcounty of Jeiferson and State 5 f-XVjseQnsin, have invented certain new and useful Improvements in Elevated Carriers;

and I do hereby declare that the following is a fnljl,; f ear, and exact description thereof.

. igMy invention has for its object to pro; ;.1 vid simpleeconomical elevated carriers each coinp nga traveler, a dump-box in vertieally-agjljustable connection with the traveler, latch-mechanism for holding the box open side upward, andlatch-trip mechanism operative 57 .51. tactwith an obstruction provided-on t he rack-for. said traveler, all as hereinafter 'articularlysetforth with reference to "hot the drawings represents a pers et ve v eivof an elevated carrier in accordianeef arra invention suspended from a k providednvith an obstruction in the the,latch-tripping mechanism perng osaidcarrier; liigpl a similar View no ahan'd'qjawl for detachable connection ratc'h jFigs.,2,' 3, and fl, details of the ;;pa ly in; section, and Fig. 5 a percw of another detail. of the carrier.

esaiioverhead Wire trackforthe'traveler e'fiin'y; improved elevated carrier, and shown Q in rigid connection with this trackis a partly depending clip I), that constitutes an obstruc- I onin the path of a strikerinvolved in latchineehanism hereinafter specified. The nearge'dge of the; depending portion of the elipis straight and its far edge is preferably egment of a circle; I i

upported on the track is a traveler coinprisingapair of tro1ley-whee1s B 5 a suitablyentf plate 0, having its ends recurvedin op- -p; ite directions; a beam D, bolted in the longer loop of the housing-plate, and a bail E, "held by clips e and nuts d on the beam be- 1 twfeen end plates c,that are bolted to said beam ijn'pairs and extend therefrom to limit possible I V sway of said bail in either direction. The 5 o' trolley-wheels are loose on axles F and these I axles engage vertical slots f in the housing end of the plate aforesaid. The slots permit npanyin gdrawings and subsequently et wlieelj constituting a detail of by letter to thedrawings, A inlimited vertical play of the housing-plate in dependentjof the trolley-wheels. To prevent turning of the axles and a cutting of same by u ,play of the Wheels aforesaid.

The bail E is preferably tubular and engaged with right-angle arms of caps g, rigid 011 the upper ends of hangers H, that 'are also for the most part preferably tubular, stop-caps or ferrules h 011 the ends of the bail servin to limit descent of the hangers.

Coupled to the bail parallel to the travelerbeam under the same are preferably tubular bearing-arms I for rollers J in connection with an intermediate preferably tubular shaft K, that rests in the loop end of plateO and has a ratchet Wheel L made fast thereon, this ratchet-Wheel being normally engaged by a detent M in pivotal connection With ears 1' of the housing-plate aforesaid. A stay-rod K is preferably extended through the tubular shaft K, bearing-arms I, and couplings I, by which these arms are connected to the hangers II, nuts being run on screw-threaded ends of the stay-rod against said couplings. Cables N are connected at their ends to the rollers J and cap-eyes of the hangers aforesaid, and said rollers are turned to Wind said cables by means of a hand-pawl I, that is engaged With the aforesaid ratchet-Wheel.

In pivotal connection with the hangers H to be top-heavy is a dump-box Q, a trunnionplate R at one end of the box being provided with a seatj fora latch S, pivotally suspended in an eye of the adjacent hanger. A vertical rod T, connected to the latch, extends through a plate 75, loose 011 another vertical rod, U, against a stop mat the lower end of same, and the upper end of rod T is bent to form a hook n, engaging the other red parallel there with. The upper end of rod U is connected to an arm of a bell-crank lever V, and an offset 1) of the other arm of said lever is pro vided with apertures engaged by rods W W that connect with a striker X, pivoted to the bent middle portion of the housing plate. Stops in the form of nuts (1 q are run on the outer ends of the rods IV N, and the pivot of the striker X is between the inner ends of said rods, the upper extremity of said striker being offset to come into contact with the obstruction b, with which the track A is provided.

At the point of loading the dump-box Q is lowered by its own weight when the detent M is lifted, and said box being set open side up the seat in the trunnion-plate R thereon is engaged by latch S, in pivotal connection with one of the box-hangers. The box being loaded it is elevated a suitable distance by means of the hand-pawl P, put into engagement with the ratehet-wheelL, the latch-rod T slipping through the plate and on the rod U when By means of the this operation takes place. traveler on track A the loaded and elevated box is run to the place of discharge, where the obstruction b is provided in connection with said track, and the striker X coming into contact with the straight edge of said obstruction there is swing of said arm to cause a lift of rod U, whereby there is bind of plate is on rod T to lift the same and unseat latch S, thus permitting. the top-heavy box to automatic ally dump its contents.

By the peculiar arrangement of the rods WV XV and stops thereon with respect to the pivotal striker X and bell-crank V it will be nn- I derstood that when one of said rods is pulling on said bell-crank the other is sliding free in the same. Hence the carrier can be run in either of two directions from the place of loading to a place of discharge and its box automatically dumped, provided there is a suitable obstruction on the track at the latter place in the path of the aforesaid pivoted striker.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An elevated carrier comprising a traveler consisting of a suitably-bent plate having its ends recurved in opposite directions, trolleywheels housed by the upper end of the plate, axles loose in the wheels and vertical plateslots, a yoke supported by said plate and engaging apertures with which the axles are provided, a beam fast in the lower loop end of the aforesaid plate, and a bail suspended on the beam; a dump-box in vertically-adjustable connection with the bail, latch mechanism for holding the box open side upward, and latch-trip mechanism in connection with the traveler operative by contact with an obstruction in connection with an overhead track for said traveler.

2. An elevated carrier comprising a traveler consisting of a suitably-bent plate having its ends recurved in opposite directions, trolleywheels housed bythe upper end of the plate, axles loose in the wheels and vertical plateslots, a yoke supported by said plate and engaging apertures with which the axles are provided, a beam fast in the lower loop end of the aforesaid plate, side plates extending from the ends of the beam, and. a bail suscables connecting said rollers and the hang-- ers, a du'nfpbox in pivotal connection with said hangers, latch mechanism for holding the box open side upward, and latch-trip mechanism in connection with the traveler operative by contact with an obstruction in connection with an overhead track for said traveler.

4. An elevated carrier comprisingatraveler, a bail suspended in connection with the traveler, rollershaving bearings on arms coupled to the bail, ashaft connecting the rollers,-a

ratchet-wheel fast on the shaftto be actuated by a detachable hand-pawl, aratchet-wheel detent suspended from the traveler, hangers guided in connection with said bail, cables connecting said rollers and the hangers, a

dump-box in pivotal connection'with said hangers, latch mechanism for holding the box open side upward, and latch-trip mechanism in connection with the traveler operative by contactwith anobstruction in connection with an overhead track for said traveler.

5. Anelevated carrier comprisingatraveler, a dump-box in vertically-adjustable connection with the traveler, a pivotal latch for holding the box open side upward, a rod connected at its lower end to the latch, and having its upper end in sliding connection with another rod depending from an arm of a bellcrank lever connected to the traveler, a plate engaged by both rods and supported on a stop with which the one depending from the bellcrank lever is provided, other rods engaging apertures in an offset of the other arm of said bell-crank lever, a striker pivoted to said traveler to come against an obstruction provided in connection with an overhead traveler-track, rods that being in connection at their inner ends with the striker in opposite directions from its pivot extend through the offset of the aforesaid bell-crank lever, and stops on the outer ends of these latter rods.

In testimony that I' claim the foregoing I have hereunto set my hand, at Waterloo, in the county of Jefferson and State of Wisconsin, in the presence of two witnesses.
